在下的毕业设计， 本题要求设计一个直流电机控制系统。在设计中，采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心，因为STC12C5A60S2内部有PCA模块，可以产生PWM波形；采用带中断的独立式键盘作为命令的输入，每当按键时蜂鸣器响；配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路，驱动能力较强，完成电机正反转以及速度的控制。为优化直流电机的响应，采用PID反馈，实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)
